▎ 摘　　要

NOVELTY - Heat-conducting wave-absorbing material with electromagnetic shielding function has a two-layer structure, the upper layer is a heat-conducting wave-absorbing gel layer, and the lower layer is an aluminum foil layer. The heat-conducting wave-absorbing gel layer includes (A) component and (B) component. The side of the aluminum foil layer in contact with the heat-conducting and wave-absorbing gel layer is etched. USE - Heat-conducting wave-absorbing material with electromagnetic shielding function. ADVANTAGE - The heat-conducting wave-absorbing material with electromagnetic shielding function used as a gap-filling material between the heating chip and the radiator of electronic products, has high shielding performance, thermal conductivity and absorption performance, also has excellent on-site construction, high stability and other characteristics, constructed in batches by machine, and at the same time avoids the consistency problem of manual installation of traditional heat-conducting and wave-absorbing materials. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a heat-conducting and wave-absorbing material with electromagnetic shielding function, which involves cleaning the aluminum foil, etch one side for later use, putting terminal vinyl silicone resin, hydrogen-containing silicone oil, thermal conductive filler, wave-absorbing filler, putting the end-group modified oligomeric silsesquioxane modifier and volatile solvent oil into the mixer according to the ratio and stir to prepare component (A) of the semi-fluid paste-like heat-conducting and wave-absorbing gel, combining phenyl vinyl silicone resin, platinum catalyst, thermal conductive filler, wave-absorbing filler, putting the polydiphenylsiloxane modifier and volatile solvent oil into the mixer according to the ratio and stirring to prepare the (B) component of the semi-fluid paste heat-conducting and wave-absorbing gel, placing the etched aluminum foil on the platform with the etched side up, mixing the heat-conducting wave-absorbing gel components (A) and (B), and then dispensing glue on the etched surface of the aluminum foil, and aluminum foil after dispensing is flattened to obtain a sheet-shaped heat-conducting and wave-absorbing material with electromagnetic shielding function.
